Three major yeasts were compared for ethanol production in batch fermentations using CPW pretreated through acid hydrolysis and a combination of acid and enzyme hydrolysis. The most efficient conditions for production of CPW-based hydrolyzates included processing at 116 °C for 10 min. Pichia kudriavzevii KVMP10 achieved the highest ethanol production that reached 30.7 g L-1 in fermentations conducted at elevated temperatures (42 °C). A zero-waste biorefinery was introduced by using solid biorefinery residues in repeated batch anaerobic digestion fermentations achieving methane formation of 342 mL gVS-1 (volatile solids). Methane production applying untreated and dried CPW reached a similar level (339-356 mL gVS-1) to the use of the side stream, demonstrating that the developed bioprocess constitutes an advanced alternative to energy intensive methods for biofuel production. | URI: | https://hdl.handle.net/20.500.14279/14860 | ISSN: | 14203049 | DOI: | 10.3390/molecules24132451 | Rights: | © by the authors. | Type: | Article | Affiliation: | Cyprus University of Technology |
